TRACK FOR DOOR-HANGERS.

Specification of Letters Patent.

REISSD Patented May 23, 1911.

To all whom it may concern:

Be it known that I, PETER FnnN'rz, a citizen of the United States ofAmerica, and a resident of Sterling, in the county of Whiteside andState of Illinois, have invented certain new and useful Improvements inTracks for Door-Hangers, of which the following is a specification.

This invention relates to that type of overhead tracks for slidingdoors, in which an extended horizontal wrought metal shell having aninturned or lateral flange at its lower edge provides a track for theusual tandem wheels of the hanger. And the present improvement has forits object to provide a simple and efficient structural formation andcombination of parts whereby strength to resist flexure of the trackwith lightness and economy of material is attained, and with whichstandard lengths of the track can be coupled togetherin a ready andeffective manner to provide a track of any desired extent, all as willhereinafter more fully appear.

In the accompanying drawings :-Figure 1, is a detail front elevation ofa track embodying the present invention, and illustrating the coup ingbetween standard lengths of the track. Fig. 2, is a transverse sectionon line sc-a', Fig. l. Fig. 3, is a similar view of a modification.

Similar numerals of reference indicate like parts in the differentviews.

Referring to the drawings, 1 represents portions of two adjoininglengths of the track coupled together by a coupling band or member 2hereinafter described in detail. In the present construction each lengthof track comprises an upper vertical attaching web 3, from the lower endof which extends outwardly an inclined shed portion or web 4, and fromthe outer end of said shed depends a vertical web 5, the lower end ofwhich terminates in an inturned and preferably trough shaped web 6 whichconstitutes the longitudinal track for the usual tandem wheels of a doorhanger, and said vertical web 5 also terminates in an outwardly extendininclined web 7, which is adapted to very e ciently brace and support thetrack against ordinary stress in actual use. It is within the provinceof this part of the present invention to make the inclined bracin(r web7 integral with the other webs 3, 4 an( 5, and secure the web 6 theretoas a separate part, as illustrated in Fig. 2 or to make the webs, 3, 4,5 and 6 integral, and secure the web 7 thereto as a separate part, asillustrated in Fig. 3.

'Ihe coupling band 2 above referred to is formed from a flat bar ofmetal bent to the outer contour of the webs 3, 4, 5 and 7 abovedescribed, and adapted to closely lit the outer surface of the same, asshown in Figs. 2 and 3.

8 is a screw passino' through the upper end of the coupling ban 2, toeffect an attachment of the track to the face of a wall o1' the like.

9 is an angle bracket arranged in the interior of the track and providedwith a vertical member adapted to bear against the wall, and an inclinedtop member that rests beneath and sup orts the inclined shed portion orweb 4 of the track. Said bracket is secured toV the coupling band 2 inspaced relation corresponding to the thickness of the web 4, by rivet-s10 and interposed washers or collars 1l, as shown.

12 is a support-ing bracket arranged underneath the track and formedwith an inclined upper arm which rests beneath and supports the web 6,and with a lower inclined arm that is secured to an adjacent portion ofthe coupling band 2, in spaced relation corresponding to the thicknessof the web 7 by rivets 1B and interposed washers or collars 14 as shown.

Vith the described arrangement of the coupling band 2, and brackets 9and 12, sockets are provided for the reception of the adjoining ends oftrack lengths, and in my preferred construction, as shown in Fig. 1, thewebs 3, 4, 5 and 7 are separated a distance equal to the diameter of theattaching screw 8, or Washers 11 and 14, while the web 6, whichconstitutes the track surface, projects beyond the otherwebs to abutagainst the next adjacent web 6, and provide a continuous track surface.

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is

1. A track member formed with an upper vertical web, an inclined webextending outwardly from the lower end of said vertical web, anintermediate vertical web depending from the outer end of said inclinedweb, an inturned web extending laterally from the lower end of saidintermediate web, and an mediate Vertical web, acoupling band formed tolit the exterior of the track l5l lengths, and supporting bracketsSecured in separated relation to said coupling band to form receivingsockets for the end of the track lengths, substantially as set forth.

Signed at Chicago, Illinois this 11th day 20 of January 1911.
